Avantor's EVP and Chief Legal Officer Claudius Sokenu Completes Sale of 1,201 Shares for RSU Tax Withholding

Details of Avantor Executive's Stock Sale

On July 24, 2026, Claudius Sokenu, Avantor's Executive Vice President and Chief Legal & Compliance Officer, executed a sale of 1,201 common shares at $11.44 per share. The transaction was disclosed in a regulatory filing with the SEC, indicating insider activity governed under Section 16 of the Securities Exchange Act of 1934. This sale was categorized under transaction code "F," signifying shares withheld by the issuer to satisfy tax withholding obligations tied to restricted stock unit vesting.

This withholding sale is a standard practice and not a discretionary market sale by Sokenu. It reflects the automatic deduction of shares to cover tax liabilities incurred upon RSU vesting, rather than a decision to liquidate holdings based on market outlook or personal investment strategy.

Understanding RSU Tax Withholding and Share Sale

The 1,201 shares sold represent the amount withheld by Avantor to fulfill tax obligations arising from the vesting of restricted stock units. When RSUs vest, executives are taxed on the value of shares received. Instead of paying taxes in cash, companies often withhold and sell a portion of shares to cover the tax bill. This transaction type is routine among publicly traded firms and distinct from voluntary insider sales.

The transaction took place on July 24, 2026, with the SEC filing made promptly on July 27, 2026, complying with the two-business-day reporting deadline for insider transactions. The sale price of $11.44 per share reflects the market value at the time of the withholding sale.

Sokenu’s Retained Ownership and Stake in Avantor

Following the withholding sale, Sokenu continues to hold beneficial ownership of 251,228 shares of Avantor common stock, designated as direct ownership. This sizable stake indicates ongoing significant economic interest in Avantor’s performance and aligns executive incentives with shareholder value creation. Such a substantial holding also remains well above regulatory thresholds that trigger enhanced disclosure or scrutiny.

Maintaining this level of ownership while serving as Chief Legal & Compliance Officer may signal confidence in Avantor’s long-term prospects and reflects alignment with shareholder interests, subject to governance and tax considerations.
